At most I "had" 4 personality disorders at the same time, narcissistic, schizoid, paranoid and one more forgot which one. All those (for me) were better explained with Asperger's. (Also it's a little funny I was supposed to be both needing people's attention, NPD, and being unaffected by it, the schizoid.)
For me my AS and ADD is one thing, it's just about where to draw the line. If you really draw a strong line I cannot identify with those with AS and not with those with ADD. In a way I don't see myself as having both, I see myself as being where they overlap. I don't for example think I have the symptoms that can happen in both, twice.
I almost know for a fact my sleep disorder is part of the neuropsych things, because those are more prone to this kind that I have.
Also my anxiety types are absolutely real, many people on the spectrum have anxiety because they are sensitive but it has not grown into specific disorders. It has with me so I do see a point in diagnosing them separately. I don't think they just happen to anybody though, I think they are rooted in my type of thinking (low latent inhibition).
I even think my somatic illness is somehow genetically related.
The diagnoses I have gone through over the years:
OCD (correct)
BPD (incorrect)
suspicion of schizophrenia (incorrect)
suspicion of Asperger's (correct but discarded)
schizoid PD (incorrect)
narcissistic PD (incorrect)
paranoid PD (incorrect)
some other PD (incorrect)
bipolar (probably incorrect)
PD NOS
depression (took me three years of severe depression to get the diagnosis! before it was seen as part of PD and "false". i was diagnosed depressed as inpatient but quickly undx'ed by my main doc) (correct but since then I'm much better in that aspect)
ADHD subtype ADD (correct)
depression with anxiety (I'm not sure how I relate to this)
DSPS (was promised to have this entered separately into my chart but doc forgot...) (correct)
Other things I have that are not diagnosed are panic disorder because even when it hits it hits really hard, I have loooong stretches when I'm not affected, GID (since I never mentioned it to a doc, subtype can be more common in AS, still quite unknown) and prosopagnosia (probably a direct result of Asperger's). Also before my depression I had a long stretch of dysthymia but it was not diagnosed.
So my real chart these days reads as follows:
Asperger's with ADD
Depression with anxiety or suspicion of bipolar
OCD
I'm OK with this "list" although I wish my doc had added the DSPS as separate even though I know where it comes from because it is quite severe.
